            Bug ID: 38328
           Summary: clang-format crash inside SourceManager on malformed
                    UTF file.
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal

clang-format < clang-format.crash results in a segfault.

clang-format crashes on a file with bad UTF codepoints. The crash itself seems
to be inside the libclang SourceManager however, which is a little weird. I've
submitted against the Formatter, but it might be a libclang SourceManager bug

cheers, Phil
